Effect of Quercetin With Oral Hypoglycemics in Streptozotocin‐Induced Diabetes, and Its Effect on Ulcerogenic Activity

AbstractA diabetic‐induced ulcer is a complication of diabetes in which the formation of an ulcer increases and also causes a delay in ulcer healing. Diabetes adds a bonus to various factors like starvation and stress, imbalanced acid‐pepsin secretions, impaired mucosal resistance, acid‐back diffusion, and neuronal dysfunction. Feeding a high‐fat diet for 15 days after induction of STZ in rats develops diabetes mellitus simultaneously with growth, resulting in an acceleration of ulcers for any of the above reasons. The OGTT investigation included both normal and diabetic rats, and the researchers establish a consistently low dosage of conventional oral hypoglycemic agents for the treatment. Clinical studies in the literature highlight that effectively treating patients with diabetes complications has been demonstrated through glycemic control. Hence, effective palliative hypoglycemic agents are employed. Long‐term usage has revealed that they exert a drastic negative effect. Hence, herbal drug combinations with these standard drugs have proved to be effective in minimizing the side effects. QE, which has hypoglycemic, dyslipidemia, and antioxidant properties, has been effective when administered with Glipizide (5 mg kg−1). The monotherapy of this Glipizide and QE has not shown a beneficial effect in protecting the stomach from ulcers. The combination (G + QE) showed effective control of glucose without any hypoglycemia. QE as a single adjunct with Glipizide has proven promising in preventing and treating diabetic ulcers.
